preparation example Construction

[0539]

[0540] The preparation of the black photosensitive resin composition is to place the aforementioned alkali-soluble resin (A), the compound having an ethylenically unsaturated group (B), the photoinitiator (C), the solvent (D) and the black pigment (E) Stir in a stirrer to make it uniformly mixed into a solution state, and if necessary, an additive (F) may be added, and after uniformly mixing, a black photosensitive resin composition in a solution state can be obtained.

[0541] Secondly, the preparation method of the black photosensitive resin composition is not particularly limited. The black pigment (E) can be directly added to the mixture composed of alkali-soluble resin (A), compound with ethylenic unsaturated group (B), photoinitiator (C) and solvent (D), and can be dispersed The photosensitive resin composition in the aforementioned solution state is formed. Or, first add part of the black pigment (E) to the mixture composed of part of the alkali-soluble resin (A)...

preparation example A-1-2 to A-1-3

[0570] Preparation Examples A-1-2 to A-1-3 use the same preparation method as the preparation method of the first alkali-soluble resin of Preparation Example A-1-1, except that Preparation Examples A-1-2 to A -1-3 is to change the type and usage amount of the raw materials in the first alkali-soluble resin, and its formula is shown in Table 1, which will not be repeated here.

preparation example A-1-4

[0572] A stirrer, thermometer, condenser, and nitrogen inlet are set on a four-necked conical flask, and nitrogen is introduced. Then, 100 parts by weight of propylene glycol methyl ether acetate (hereinafter referred to as PGMEA) was added to the four-necked Erlenmeyer flask, and the temperature was increased to 100°C. Next, 10 parts by weight of diethyl-2,2'-[oxybis(methylene)]bis-2-acrylate (hereinafter referred to as DEOA) and 25 parts by weight of dicyclohexyl-2,2' -[Oxybis(methylene)]bis-2-acrylate (hereinafter referred to as DCOA), 40 parts by weight of acrylic acid (hereinafter referred to as AA), 25 parts by weight of benzyl methacrylate (hereinafter referred to as BzMA ) And 4.5 parts by weight of 2,2'-azobis(2,4-dimethylvaleronitrile) (hereinafter referred to as ADVN) were dissolved in 100 parts by weight of PGMEA, and the mixed solution was gradually added within 2 hours Drop into a four-necked erlenmeyer flask. After reacting at 100°C for 6.5 hours, 1 part by wei...

Abstract

The present invention relates to a black photosensitive resin composition, its use, and a black matrix and / or black gap formed by the black photosensitive resin composition to manufacture a color filter and a liquid crystal display module. The said photosensitive resin composition contains the alkali-soluble resin (A), the compound (B) which has an ethylenically unsaturated group, a photoinitiator (C), a solvent (D), and a black pigment (E). The black matrix and / or black spacers formed of the black photosensitive resin composition according to the present invention have the advantage of nodevelopment residue.

Description

Technical field [0001] The present invention relates to a black photosensitive resin composition, and a black matrix and / or black spacer formed by using the black photosensitive resin composition to manufacture color filters and liquid crystal display components; in particular, to provide a black A photosensitive resin composition and its application. The black matrix and / or black spacer formed by the black photosensitive resin composition has the advantage of no development residue. Background technique [0002] In recent years, with the vigorous development of various technologies of liquid crystal displays, and in order to improve the contrast and display quality of the liquid crystal display, a black matrix is ​​usually set in the stripes and stripes of the color filter in the liquid crystal display. In the gap between dots. The black matrix can prevent defects such as a decrease in contrast ratio and a decrease in color purity caused by light leakage between pixels. In add...
